Bathroom air-conditioner

a technology for air conditioners and bathrooms, applied in lighting and heating apparatus, ventilation systems, heating types, etc., can solve the problems of reducing the efficiency of air conditioners and increasing heat collection, so as to reduce the loss of heat dissipation to the air discharged from the bathroom to the outside, reduce the amount of air blowing, and increase the enthalpy efficiency of radiators.

Abstract

A bathroom air-conditioner includes a refrigerant circuit in which a compressor, a radiator, a decompressing mechanism and a heat absorber are connected with one another through a pipe, a circulating air-course, and a ventilating air-course. In the circulating air-course, the radiator and a circulating fan for circulating the air of the bathroom are placed. In the ventilating air-course, the heat absorber and a ventilating fan for discharging the air from the bathroom to the outside are placed. The heat absorber makes the refrigerant absorb heat from the air of the bathroom, and the radiator makes the refrigerant dissipate heat to the air of the bathroom for heating the bathroom. During the heating of the bathroom, when a temperature of the bathroom becomes higher than a given temperature, a controller reduces an air-blow amount from the ventilating fan.

Description

TECHNICAL FIELD

[0001] The present invention relates to a bathroom air-conditioner for air-conditioning a bathroom by using a heat pump.BACKGROUND ART

[0002] A conventional bathroom air-conditioner using a heat pump has worked this way: A first heat exchanger of the heat pump radiates or absorbs heat to / from the air drawn from the outside of the bathroom, and then blows out the air into the bathroom. A second heat exchanger of the heat pump absorbs or radiates heat from / to air evacuated from the bathroom to the outdoors. The bathroom has been thus air-conditioned (refer to, e.g. Patent Document 1).

[0003] The foregoing air-conditioner collects the heat from the air to be discharged from the bathroom to the outdoor, and gives heat to another air drawn from a place other than the bathroom, thereby air-conditioning the bathroom. A continuous operation of this air-conditioner sometimes generates a difference in enthalpy between the air drawn from a place other than the bathroom and the air in...
